MASK.

Application filed. January 12, 1825, Serial No. 2,026. Renewed October 10, 1927.

This invention relates to inhalers especiallyv adapted to the use of chlorine gas mixed with air in the treatment oi' respiratory passages.

In the use oi' chlorine gas and air for the treatment of colds, influenza, whooping cough and other respiratory diseases, the patient is placed in a closed roomv and a given number (for example 1200) litres` of air mixed with chlorine gas, per minute, is distributed within theA room, the purpose being to provide a concentration of 0.015 milligrams per litre, that being the amount best suited tor the purpose. Should the concentration be much below 0.015 milligrams, it will prove ineffective, while a concentration above (for example 0.017 grams) causes irritation.

It is of course a relatively simple matter to introduce'enough chlorine gas into a room to provide a. concentration ot' 0.015 milligrams, but it is obvious that some of the gas will be absorbed by the walls, hangings and fittings of the room, as well as the clothing, hair and body ot' the patient, so that by the present method it is practically impossible to regulate the treatment so that the patient will receive an exact amount. Another disadvantage of the present treatment resides` in the fact that the patient must remain confined in a room for a long period of time for a single treatment.

The above and other disadvantages are overcome by the present invention in which the chlorine gas in measured quantities is .mixed with air and administered so that the patient receives a definite amount at each treatment and receives it in regulated quantities without being coniined within a closed room, so that the air mixed with the gas will be fresh instead of air breathed by a number ot patients simultaneously receiving treatment, as is the case with the method ot treatment now in vogue.

With the above and other objects in view, the invention 'further includes the following novel features and details ot construe tion. to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a sectional view showing an inhaler constructed in accordance with the invention, in position for use.

Figure 3 is a section on i Figure 1.

Figure 1 is a similar view on the line 4-4 of Figure 1.y

Figure 5 isl a detail perspective view of the regulating valve.

Referring to the wherein like characters of reference denote corresponding parts, the reference character 10 indicates a mask which is shaped to it closely about the face overthe nose and mouth of a patient so as to provide a breathing chamber 11. Extending forwardly from 'the mask 10 is a conduit or passage 12 having an outer open end 13 for the admission of air. The conduit or passage 12 extends within the breathing chamber 11 and is provided with a check valve 111.A This valve is in the ferm oi a perforated cap 15 and a disk 16 which is located within the cap. This disk is adapted to rest upon the inner end of the conduit or passage 12 when the patient exhales so as to close the inner end ot this passage, but is liftedfrom this seat when the patient inliales so as to establish communication between the passage and breathing chamber. The mask is provided with a check valve 17 which is similar to the valve 14 in that it consists oit' a perlorated cap 18 and a movable disk 19, the latter` acting to close the valve when the patient inhales and to open the valve when the patient eXhales. The caps 15 and 18 ot' the valves maybe removed and replaced when desired. y

Located between the breathing chamber and the passage 12 is a container 20 which is provided `with a removable closure 21. This closure includes a flange or skirt 22 which extends downwardly int-o the container20 and which is provided with an opening 28, the latter being adapted to register with an opening 24 which provides communication between the container and the passage 12. The closure 21 is provided with a lug 25 which is movable within an arcuate recess upper edge of the container, one Wall of this groove being notched as shown at 27 in Figure 2 of the dra-wings so as to permit of the passage of the lug 25 for the purpose of removing or replacing the closure 21.

or groove 26 provided adjacent they the line 3-3 of i drawings in detail f lill) The closure includes; a beveledjiinge .28 which isvprovided With graduations 29, the latter being adapted to be positioned with respeetto. Le stationary indicator 3Q, ,for .deterlniningptbe relativepositions of the openings 23 and 24.

The closure 21 is provided with a lrnurled knob 31 by ineens of which the said closure may be rotated, Wblilexzui opening 32,*elzrtending' through the closurefiprovldes a vent.
